I work in a company. Me and my one of the employee have developed attraction for each other. I am her manager/ employer and she is my subordinate. We are planning to have consensual physical relationship with out marriage. But, my concern is if things go wrong in the future , I do not want to falsely get charged with sexual harassment and no body should able to allege that i used my position as manager/ employer to pressure her or forced her to have sexual relationship. I am thinking about having a sort of written contract which both of us will sign which will protect me from false allegation in the future. Off course I want to do it confidentially.
